Remote Control Unit – 1
1. The System
The RCU-1 is a practical remote-control and program unit for all new-generation ARRIFLEX cameras: from the ARRIFLEX 16SR 3 through the 535 and 535B to the new ARRIFLEX 435.
Its range of functions is automatically adapted to the attached camera: at both operating speed value limits and on an electronically adjustable mirror shutter. The RCU-1 can be used whenever uncomplicated, sturdy, and yet still comprehensive remote control is important.
With the RCU-1 the synchronisation of the filming speed with the opening angle of the shutter provides an easy exposure compensation. Complete programs can be created to control the co-ordinated change of speed and opening sector over a chosen period of time. These programs may be recalled by the push of a button whenever needed. The RCU-1 also automatically calculates the actual screen-time for all programmed ramping functions.
An optimal control and precise adjustment of values is easy with the big handwheel. The free programming of its end stops to individually defined minimum and maximum values is also extremely comfortable.
An illuminated liquid crystal display accurately and comprehensively shows the set values and the camera status with all warning indicators.

Remote Control Unit – 1
Range of Functions
The RCU-1 combines two modes of operation in a compact housing:
•CAM-functions
In the CAM-mode exactly the same operational modes and functions are accessible as directly on the camera itself. The display of the RCU-1 shows the same information as the camera display. The keys MODE, SEL, SET, RUN, RAMP and the RUN-LED have the same function as the equivalent operating elements on the camera.
In this mode the RCU-1 serves as a pure remote control without its own programming possibilities.
•RCU-functions
Additionally the RCU-1 offers easy programming and a convenient manual setting of filming speed and shutter angle.
5
Remote Control Unit – 1
RCU-1 operating modes are:
)
to control the shutter angle manually with the handwheel on cameras with an electronically adjustable mirror shutter.
The end-stops for the handwheel can be programmed to cover a user-defined range of the shutter angle.
fps
for the direct control of the filming speed with the handwheel.
The end-stops for the handwheel can be programmed to cover a user-defined range of filming speeds.
ramp
for the easy programming and the recall of automatically controlled speed ramps
with a user-defined ramp duration.
fps + )
for a manual control of the filming speed with the handwheel and an automatically synchronised mirror shutter adjustment for constant exposure. The end-stops for the handwheel can be programmed to cover a user-defined range of filming speeds.
ramp + )
to program and recall automatically controlled speed ramps with a user defined ramping-time and an automatically synchronised shutter angle adjustment for constant exposure.
6
Remote Control Unit – 1
In RCU mode, the display of the RCU-1 shows the current values of the correspondent RCU modes. The MODE, SEL, SET and RAMP key relate only to the chosen RCU function. The available ranges for filming speed and shutter angle are automatically recognised and supported for all connected ARRIFLEX cameras.
•The Iris Control Unit (ICU) may be used for cameras without electronically controlled mirror shutters for constant exposure in the ramp function.

2. Setup
2. 1 Electrical Connection
The RCU-1 is connected to the CCU-socket on the camera with the cable KC-39 (1.5 m), or the cable KC-41 (20 m). This serial RS 232 interface transfers all data precisely and is not sensitive to interference.

2. 2 Switching on
The RCU-1 does not have its own on/off switch. It is supplied directly through the camera via the connection cable, as soon as the camera is switched on. The display of the RCU-1 illuminates red as long, as the camera is on.
The READY-LED changes from blinking red to permanent green, once the communication has been successfully established. The RCU-1 is now ready for use.
2. 3 Important Notes
•Do not edit speed values on the camera, when operating in the RCU mode, as these values are going to be constantly overridden by the RCU-1. The RCU-1 is an active unit, and its settings are predominant to the settings of the camera. The camera retains the values which had been set with the RCU-1. This applies for switching back from RCU to CAM mode, as well as if the RCU-1 is disconnected from the camera.
•All selected parameters, programs and user defined end-stops are stored in the RCU-1 even if it is disconnected. Therefore it is possible that user defined end-stops programmed into the RCU-1 are not available with a currently connected camera – i. e. end-stops have been programmed for a highspeed camera and the RCU-1 is later used on a regular production camera. The RCU-1 automatically recognises the connected type of camera, but does not automatically change programmed values.
9
Remote Control Unit – 1
If the set values exceed the available range for the currently connected model, a warning indication is displayed.
Important:
In RCU-mode the RCU-1 overrides the values for filming speed and shutter angle set at the camera. This may result in a wrong exposure for the subsequent takes if the values are not checked before you go on filming.
A value for the shutter angle set with the RCU-1 is retained in the camera. The shutter angle will not be automatically readjusted to 180°.
All ramp functions programmed with the RCU-1 are stored directly in the remote control unit, and not in the camera. The RAMP-function is therefore not identical with the program-function on the camera. It is also different from a program edited with the CCU and stored in the camera afterwards.
Do not use the Iris Control Unit (ICU) simultaneously with the RCU-1 in RCU mode on a camera with an electronically adjustable mirror shutter. This may cause incorrect exposure.
Disconnect the ICU before using the RCU-1.

3. CAM Functions
CAM
RCU
position CAM
The operating elements on the RCU-1 control the same functions as the correspondent keys and indicators on the camera:
MODE • SEL • SET • PHASE, RUN-key and RUN-LED.
The RAMP key represents the “program“-function of the camera in this mode of operation.
All camera functions are explained in the corresponding instruction manuals of the cameras.
In CAM position the display of the RCU-1 shows exactly the same information as the display on the camera.
It is highly recommended to switch the RCU-1 into the CAM position before connecting it to the camera, if only CAM functions are used. This ensures that no filming speed or shutter angle set on the camera is overridden in switch-position PS/CCU on the camera and in RCU mode on the RCU-1.
In RCU mode the RCU-1 overrides all settings of the camera for these values. (see Important Notes).
Ramping programs, stored in the camera with a CCU are not affected.
